Description

음극선관Cathode ray tube

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명의 1실시예에 의한 음극선관을 도시한 분해사시도,1 is an exploded perspective view showing a cathode ray tube according to an embodiment of the present invention,

제2도는 새도마스크의 일부를 도시한 정면도,2 is a front view showing a part of the shadow mask,

제3도는 제2도의 Ⅲ-Ⅲ선을 절단한 단면도.3 is a cross-sectional view taken along the line III-III of FIG.

Claims (1)

관본체(1)의 네크부(1a)에 내장딘 전자총(2), 상기 관본체의 패널부의 내면에 부착된 형광면(3) 및 상기 전자총과 형광면 사이에 배치되며, 또한 여러개의 전자빔 통과용의 구멍을 갖는 새도마스크(4)를 마련하고, 상기 전자총(2)에서 발사된 전자빔이 상기 새도마스크의 구멍을 통과해서 상기 형광면에 입사하도록 구성되어서 이루어지는 음극선관에 있어서, 상기 새도마스크의 구멍 주위에 새도마스크(4)의 재료보다 투자율이 높은 재료로되는 자기실드총(10)을 형성한 것을 특징으로 하는 음극선관.An electron gun 2 embedded in the neck portion 1a of the tube body 1, a fluorescent surface 3 attached to the inner surface of the panel portion of the tube body, and disposed between the electron gun and the fluorescent surface, and for passing several electron beams. In the cathode ray tube formed with a shadow mask 4 having a hole, and the electron beam emitted from the electron gun 2 passes through the hole of the shadow mask and enters the fluorescent surface, A cathode ray tube, characterized in that a magnetic shield gun (10) made of a material having a higher permeability than a material of a shadow mask (4) is formed around the hole. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
